I would recommend finding a budget before getting too far into this. There are a lot of variation in the quality and performance of monitors. Decent gaming monitors vary anywhere from $150 (Asus VE247H) to $900 (Asus PG279Q ROG Swift). I would recommend running either 3x Asus VG248QE or 1x Asus ROG Swift. I recently read this article that reviews several gaming monitors.

I am also wondering what your guys' opinion is about the Asus VG248QE verse the Asus VS278Q-P. The VS278Q-P is only 60Hz, but do you guys think it will work for games that don't require a really fast refresh rate?
